Holiday Inn hotels hit by card payment system hack

One expert said there might be further hotels affected. Buckinghamshire-based IHG had previously reported in February that a dozen US hotels that it managed itself had been affected by the same attack. IHG said an investigation had detected signs the malware had been active at front-desk payment locations at the hotels between 29 September and 29 December 2016. The attack hijacked information taken from the payment cards' magnetic strips as it was being routed through the hotels' computer servers, said the hotel group. Other hotel chains to have been struck by payment system hacks in recent years include Hyatt, Mandarin Oriental and Trump Hotels.
